Description

The present invention relates to fluid dispensers, systems, kits, and methods thereof.

Fluids are often packed, stored and discharged in bottles, such as plastic bottles. However, such bottles have some drawbacks. Large volumes of packaging are required for shipping, and large spaces are required for storage due to the bulky and inflexible bottles. Due to the design of the bottle and / or the structure of the discharge means for sucking the fluid from the bottle, a large amount of fluid cannot be reached, and sometimes 10 to 20% or even 50% of the fluid is discarded as waste. In addition, since empty bottles after use are bulky and inflexible due to the nature of the bottles, they consume a large amount of space in consumers' trash cans, recycling boxes, landfills, recycling centers, and the like. Improved fluid dispensers are needed, at least for these constraints.

In particular, it is required to provide a liquid dispenser having higher versatility as compared with conventional plastic bottles. It is also necessary to provide a liquid dispenser in which most of the fluid can be sucked out. It is also necessary to provide a liquid dispenser in which non-disposable parts, such as outer containers, are reusable, thereby reducing overall waste. It is also necessary to provide a liquid dispenser with a reusable fluid container, thereby reducing overall waste. It is also necessary to provide a liquid dispenser with a disposable liquid container made of weight loss packaging material, especially as compared to conventional bottles, thereby limiting the storage space required. There is also a need to provide a liquid dispenser that provides a platform for customization, branding, or advertising, thereby allowing the discharge of various fluids.

It comprises a flexible container adapted to contain the fluid, a rigid outer container adapted to contain the flexible container, and a discharge member for sucking the fluid from the flexible container. Fluid dispensers are disclosed. The flexible container, the rigid outer container, and the discharge member are attached together either directly or indirectly to form a component of the fluid dispenser. Each component comprises one or more elements. The fluid dispenser may also be equipped with additional components such as interconnect components. Depending on the envisioned situation and application, all or part of the components of the fluid dispenser may be assembled together. For example, a ready-to-use fluid dispenser typically comprises a flexible container, a rigid outer container, and a discharge member, the flexible container being or will be filled with fluid. The dispenser may include an empty flexible container, a rigid outer container, and a discharge member.

Flexible containers require much less space and use less material than traditional bottles, allowing them to be packed tightly and require less packaging and storage space. The flexible vessel design allows for suction of more fluid, and in some cases up to 99% of the fluid, thus reducing waste. In addition, since the flexible container after use is refilled and reused, the total amount of waste can be reduced. Alternatively, the flexible container may be disposable, and such a disposable flexible container uses less material and occupies much less space in the recycling center than traditional bottles. .. The rigid outer container of the fluid dispenser is reusable, providing a platform for customization, branding, and advertising. The discharge member may be disposable or reusable.

The feed opening may be provided with locking means for engaging the neck of the flexible container, either directly or indirectly. The locking means is adapted to limit the horizontal, vertical, and / or rotational movement of the neck of the flexible container, the connecting parts of the discharge member, or the interconnecting parts. The width of the recess can be slightly smaller than the diameter of the neck, the connecting or interconnecting parts of the discharge member. In that case, the neck, discharge member connection parts, or interconnect parts may have sufficient flexibility to be slightly deformed when secured in the recess. Alternatively, the width of the recess can be substantially the same as or larger than the diameter of the neck, the connecting part of the ejection member, or the interconnecting part. In such cases, the annular ring as defined herein may be placed on the neck, a connecting part of the discharge member, or an interconnecting part.

The discharge member may then further be equipped with pumping means. The discharge member may be selected depending on the type of fluid being discharged. Spray pump appliances can be used with low viscosity fluids. Lotion pump type equipment can be used with high viscosity fluids. Pumped devices may include transfer tubes, connecting parts, and movable heads.

The discharge member comprises a connecting component for attachment to the neck of the flexible container. The connection parts of the discharge member can be attached directly to the neck of the flexible container. Alternatively, the connecting component of the discharge member may be indirectly attached to the neck of the flexible container via the interconnecting component as defined herein. Any conventional means may be used to attach the connecting means, or interconnecting parts to the neck. Suitable conventional means may be selected from thread, bayonet, or clipping. The connecting part or interconnecting part can be an annular collar. The annular collar may have an internal thread designed to engage the corresponding external thread on the neck.

The connecting part can optionally be reversibly attached to the neck of the flexible container via the interconnecting part. In such cases, the flexible container can be removed after use and the discharge member can be reused. Alternatively, the connecting component can optionally be irreversibly attached to the neck of the flexible container via the interconnecting component. In such cases, both the flexible container and the discharge member are discarded after use.

The connecting parts can have any suitable shape and dimensions. In some embodiments, the connecting component may have an elongated shape for projecting the movable head over a rigid outer container at a distance. Elongated connections may also be suitable for covering the pump.

The movable head may have a radially protruding outlet from which fluid is ejected during operation.

The transport tube can be flexible or rigid. The transport tube may be straight, angled, or curved. In some embodiments, the transport tube is long enough to reach or near the bottom of the flexible container. This makes it possible to eject most, and even almost all, from the flexible container. In an alternative embodiment, the transport tube is shorter than the length of the flexible container, eg, about two-thirds of the length.

Interconnectors Fluid dispensers may further comprise interconnectors. The interconnect component can be used to interconnect (attach / engage / secure) at least two components, in particular interconnecting the neck of the flexible container and the connecting component of the discharge member.

A reversible fit of at least a portion of the annular ring of the flexible container, discharge member, or interconnect with the supply opening of the rigid outer container is the flexible container, discharge member, or interconnect. Limits horizontal, vertical, and / or rotational movement of the neck within the supply opening.

The outer surface of the annular ring may have a circular cross section or a square cross section. The square shape can be selected from a triangular shape, a square shape, a pentagonal shape, a hexagonal shape, or any other suitable shape.

Reversible fitting of at least a portion of the annular ring of the flexible container, discharge member, or interconnect component to the supply opening of the rigid outer container can be achieved in different ways.

The neck of the flexible container, the connecting part of the discharge member, or the interconnecting part may include one annular ring. The annular ring may be positioned at the neck to form a gap with a constant height between the bottom of the annular ring and the top of the container portion. The height of the gap may be approximately equal to or approximately equal to the thickness of the portion of the rigid outer container forming the edge of the supply opening. Alternatively, the height of the clearance may be lower than the thickness of the portion of the rigid outer vessel forming the edge of the supply opening, thereby the material constituting the annular ring and / or the top of the vessel portion. Some degree of flexibility is required. Alternatively, the height of the gap may be higher than the thickness of the material forming the edge of the feed opening.
